When using Tasmota WebInstaller which uses esp-web-flasher under the hood flashing does work.

Maybe the C3 stub is incorrect and so gets stuck once written to RAM https://github.com/espressif/esptool-js/blob/main/targets/esp32c3.js

Having the same issue with ESP32-C3. Bumping for visibility.

@brianignacio5 Can you implement in your PR?

[igrr]

This should be now fixed by #54, thanks @liux-pro!

@igrr still not fixed, exactly the same issue as @Jason2866 esp32c3 via build-in usb jtag

[igrr]

I thought I tested the final merge commit on both C3 with USB_SERIAL_JTAG and CP2102, but looks like I didn't.

Updating the stub binary seems to solve the issue. I'll do more checks with different boards and open a PR.

[igrr]

@liux-pro may I ask you to try https://github.com/espressif/esptool-js/pull/65 and see if that fixes the issue on your end? I've only updated the stub binary for ESP32-C3 there.

Fully functional !

Confirmed working with PR #65 Good for release when debugging Infos #63 are removed.

#65 has been merged, hopefully this is fixed for good!
